Deadly storms hit Midwest

A pedestrian crosses flooded Illinois state route 161 in Belleville, Ill., April 18, 2013, after a quarter mile stretch of the road was quickly covered in water from heavy rains that were too much for the storm drains to handle.

Much of the Midwest has been affected by a big spring storm that left flooding in Illinois. Residents in Gurnee, Ill., said it's the worst flooding they've seen in a decade and officials are warning it could be a week or two before flood levels significantly drop. NBC's John Yang report.
